Five Things You Need to Know Today: April 30

1. Special Senate primary. Today is the special primary for the U.S. Senate seat vacated by Secretary of State John Kerry. There will be both a Democratic and Republican primary today and the two winners will go head-to-head in the June 25 special election. Check out our Newton Election Guide for everything you need to know before heading out to the polls today. Remember, polls are open 7 a.m. - 8 p.m. 

2. Blood drive. The American Red Cross will host a community blood drive today at the Newton Health Care Center, 2101 Washington St. The blood drive will be held from 2 p.m. - 7 p.m. To schedule an appointment, call 1-800-RED-CROSS (733-2767) or visit redcrossblood.com.

3. "Stress and Resilience in Children." The Jackson-Walnut Park Schools will welcome Dr. Leonard Sax this evening for a lecture titled "Stress and Resilience in Children." The presentation will touch on the "confusion" many parents have about the difference between self-esteem and resilience, and why resilience is more valuable than self-esteem. The free lecture will be held in the Aquinas auditorium, 15 Walnut Park, at 7 p.m.

4. Reminder: Nomination papers. Nomination papers for Newton's fall municipal election will be available in the Election Commission Office starting tomorrow, May 1.
